Sandra Bullock headed to Charlize Theron's house on Sunday to enjoy a very festive PAR-TAY with her son, Louis, and from the looks of how happy they seemed… it appeared as if they couldn't wait to get cake wasted!
As the mommy-son duo walked up to the actress' door, Sandra held a BIG gift, while little Louis carried his race car.
We bet these two had oodles of fun because Charlize probably knows how to throw a great bash.
After all, blondes always have more fun, right?!? LOLz
